Abstract

The invention relates to a power communication network vulnerability evaluation and routing optimization method, and belongs to the technical field of power communications. The method comprises the following steps: modeling a network topology of a power communication network, and defining the power communication network as a weighted undirected network; establishing a vulnerability evaluation model of a node and a side according to a topology vulnerability factor, a business vulnerability factor and an equipment vulnerability influencing the vulnerability of the node and the side, and evaluating the vulnerability of the power communication network according to the vulnerability evaluation model. The factors influencing the vulnerability of the node and the side are summarized as three factors of topology vulnerability, the business vulnerability and the equipment vulnerability, and a comprehensive vulnerability index is obtained according to the relation of above mentioned three factors, thereby comprehensively displaying the vulnerability size of the node and the side, and improving the vulnerability evaluation accuracy of the power communication network.

Description

technical field [0001] The invention relates to a vulnerability assessment and routing optimization method of a power communication network, which belongs to the technical field of power communication. Background technique [0002] The power communication network is an indispensable and important part of the power system. It is the basis for power grid dispatching automation, network operation marketization and management modernization, and an important infrastructure for the development of smart grids. Power communication services such as relay protection, stability control, and distribution automation carried by power communication networks are closely related to power production. Once a failure occurs, it will pose a threat to the stable operation of the power grid. Therefore, it is important to carry out research on the vulnerability of power communication networks. meaning. [0003] Different from the definition angle of reliability and other indicators, vulnerability ...
